Application filed June 29,

To all whom it may concern:

Be it known that I, Jonzv L. Wnenuzn, a

citizen of the United States, residingin the city of St. Louis and State of Missouri, have I invented new and useful Improvements in Resetting Mechanism, of which the followin is a specification.

his invention relates to resettin mechanisms. and the invention is particu arly appliciih le to odometers. While features of the invention may be applied to odometers of other kinds, the invention is especially useful when applied to an odometer having number wheels which are freely :rotatable.

The general object of the present invention is to provide means to prevent'the disturbance of the position of the number wheels when the automobile is backed, and

also to provide a single hand-operated mom-,1

ber forefi'ecting the resetting movgnent: of 'the indicator to zero, and for sett'mg up the indicator-"to any. desired reading. This latter function is very useful in making atripin an automobile, because sometimes the driver of the car will make a mistake in a turm'nnd find that he must re- Aurn to a point where he left his proper route. When this occurs, he may wish to alter the reading of the trip register: so as 80,40 eliminate the mileage which occurred wh en'the automobile left the proper road. My invention is admirably adapted for'use "n such a case,

ting mechanism to be readily employed to set the number-wheels of the register to indieate any desired amount. A single handoperated thumlrhead may be used" either to reset the number wheels to "zero, or -to alter'the reading of the n'umber wheels at 00 will," Further objects of the invention will appear hereinafter. p

The invention consists in the novel features, and ,in' the. eneral combination of to be particu a'.'ly described herein. after, all of which contribute to produce a simplejand etlicient resetting mechanism. A re erred embodiment of my invention will we particularly described in the following 00 specification, while the broad scope of my invention will be pointed out in the appended claims. f

because it enables the reset,

In the drawing, 1 represents the dash in which the odometer 2js set so as to be withr the window 5. My invention concerns the means for resetting and controlling by hand the number wheels of the trip indicator.

The preferred construction of the trip indicator is clearlyshown in Figure 3 which is a vertical section on the line 3-3 of Figure 1. This indicator includes a plurality of mileage indicating number wheels 6, 7 and 8, the last of whichis the wheel of lowest denomination, in the resent instance, a fraction wheel, Three w eels will give the tri mechanism a capacity of one hundred mi es, but if desh'ed, there may be any number of these wheels to give the trip mechanism any capacity desired. The fraction wheel 8 IS driven in the regular way in the forward direction by some part of the automobile, for example. a gear wheel (not illustrated) which meshes with a gear wheel 9 (see Figure 5). In other words, when the automobile is running forward. this gear wheel 9 is continuously rotated in the direction of the arrow shown in Figure 5. Therefore, this wheel 9 constitutes a part of the driving means for driving the wheel 8 of lowest denomination.

The driving means however, also includes a one-way driving connection preferably of the form indicated in Figure 5, and consisting of a thin disc 10 of metal, which is secured rigidly to the side of the number wheel 8, and has a resilient tongue or pa-wl I1 which may engage with any'one of a plurality of notches or recesses 12 formed in the adjacent face ofthe gear 9; that is to say,

this part 11 is merely a spring-pawl against the end of which the end of one of the notches 12 thrusts to drive the wheel 8 in-a forward direction. With this construction, it will be evident that if the wheel 8 were held against rotation. the gear wheel 9 could rotate backwardly if the automobile were backed, without rotating the number wheel 8. Any suitable carrying mechanism may be provided, for carrying between the wheels. In order to enable thisto be accomplished, rigid with the wheel 8, I provide a car-. ricr wheel consisting of two discs 13 and 14, the former of which has two teeth 15, and the latter of which has a single tooth space 16, (see Figure 6). Extending along the side and parallel with the axis of rotation of the number wheels, I provide a carrier shaft 17 with loose carrier pinions, such as the-pinion 18. At each rotation of the number wheel 8, the pinion 18 is rotated and imparts a movement to the number wheel 7 through one number space. This is aooom lished by means of'a ar wheel 19 rigid with the number wheel and meshing with the pinion 18.

This mechanism is duplicated between the wheels 7 and 6 in order to enable the carrymg to be effected from the unit-wheel to the tens-wheel. By a similar carryingdevice the tens-wheel carries over to the wheel 0 lowest denomination of the total indicator .also operates as a support for the driving gear 9, that is to say, the driving gear 9 is rotatably mounted on this sleeve. It is necessary tohave the gear wheel 9 loose on this sleeve, otherwise the'driving connection to this gear would prevent the rotation of the sleeve. and the number wheel 8, by .hand.

I provide a hand-operated rotatable member mounted so as to shift into two positions, and I provide means for driving" the outer sleeve from the hand-operated .me'mbe'r-in one of'these positionsto rotate the outer sleeve, and the lowest denomination wheel in the forward direction; and I providemeans actuated by the hahd-operatedmember in its other sition, fori'xfiotating a pick-up shaft in a forward directionso as tocmoperate with pick-up devices correspondingto each number wheel {that is t'o'say, I provide means on the pick-up shaft'which operates to hold the. number-wheels withtheir zeros aligning tOgethe threby enabling 'the hand-operated member to':.reset.'the -number wheels to zero." In order to gprevent the ick-up shaft frombeilig rotated when'the owest-denomination wheel is being 'rotated in a forward direction by the hand-operated member, I provide special m'eansto prevent such rotation, and this- S ecia'l means. not only operates to preventji-t epick-up shaft from rotating in the'forward direction, but it also prevents the automobile from turning the number wheels from their itionjn case the automobile is driven bac wards Tothis end, I provide a pick-upshaft which is in the form of a, tubular shaft or inner sleeve :21 rotatably mounted within the outer sleeve 20. Each carrier wheel 13 is provided with a pick-up device consisting of a pawl 22pressed by a spring 23; and. op posite each pawl 22, the pick-up shaft. 2t 18- provided with means to co-o rate with the pawl to enable the pick-up sfaft to engage the pawls to rotate the wheels 13. This means is in the form of a disc 24 with a notch having an inclined edge and an abrupt edge or shoulder 25 (see Figure 4).

The number wheels carry these pawls 22 at the same point with to the numberson the wheels so that if the pick-up shaft is rotated in the direction of the row indicated in Fire 4. the shoulders and the pawls 22 will cooperate tohold all the num r he s ith. their zeros aligning number wheels to zerh, The number wheel 6 is mounted on its. corresponding outer sleeve 40, while the, number wheel 7 is mounted on its corresponding outer sleeve 41. l

a As the outer sleeves 20, 40 and 41 are all freelyrotatable on the inner sleeve 21, it will be evident that if the number wheel 8 were given a backward rotation by driving the automobile backwards, the rot'tion of its sleeve might operate to give a backward rotation to the inner sleeve 21 a d thereby rotate the number wheels 6 and 7 in a backward direction. Such a backward rotation of the number wheel 8 could easily occur -because the spring tongue 11 might cause thenumber wheel 8 to rotate bac with the,gearwheel 9. or this reason, it is necessary to provide means for preventing a ban and tion of the pick-u shaft 1f utomob: p

In orde provide means for, reven n these/accidental or unintentiona rotatibns thcr, and so that a further rotation in this direction will enable the number wheels to be all reset to zero simultaneously. In order to place the rotatable hand-opera-ted member in'aiposition to be 'convcnient-ly operated, I prefer to place it just in front of the dash 1 and construct it in the form of a m-illedthumb-head 26. This head is rigidly attached to an o ratin spindle or stem 27 which is mounte to sli e in and out in a'bushing 28. This bushing 28 is rotatable, but is held against sliding longitudinally. Furthermore, this bushing has a gear wheel 29 meshing with a; gear wheel 30 attached'to an extension-sleeve 31 which is coupled to the outer sleeve"20, at the point 32 so that when the extension 31 is rotated, the outer sleeve 20 will also be rotated.

I provide clutch means for enablin .the 20 stem 21w connect with the outer 5 eve when the stem is ulled outwardly. For this purpose, the bu ing 28 is provided with teeth, such as the tooth 33 which is adapted to be engaged by a cross-pin 34 carried by. the stem, whcn'the stem is pulled out?! device whi preferab yiii'tlidfforhihf wardly The innersleeve 21 is provided with ,frictionatdevioe.

For this verticall in a. guide-cap 44 and v y by av coi spring 45 so new holdtliel he i purpose, the, upper end "of the bushing-or sleeve 38 is provided with-'teetb,xsuch as ifi-mesh Wldleflfih other. i, I The disc 43 has a dog .46 on its edgle which the tooth 39, which is adapted to besen- 'of-the' gagedb x the cross-pin 34 when the stem is received in atgroo've 47 in the we cap to prevent a disc from rotating.

In addition to this, if backward rotation ofthe gear wheel 2-- ment at the window 5. 0

It will be evident that as the inner sleeve should occur by backing the" automobile, and

backward rotation isftherebv imparted to a ios inner sleeve or 21 fits rotatably in the outer sleeve 20, the

rotation-of the outer sleeve in the forward dire'ction by means of the thumb-head 26 might impart rotation to the inner sleeve 21 and thereby unintentionally through the operation of the pi -k-up devices, align all the the number wheel 8, this backward rotation cannot rotate'the pick-up shaft 21 in i a backward'diroction because a rotation of the p -u shaft in this direction would involve the rotation ofthe sleeve 38 in aclockwise direction; this would be positively prevented by the teeth on the disc 43.

Figure 9 shows the construction of the extension sleeves 3t and 35 at the point 32 where they form a joint with the sleeves and 21. In order to form this joint, the extension sleeves 31 and 35 are formed with diametrically opposite tongues 31' and 35 which are received in corresponding slots formed in the ends of the other sleeves.

It is understood that the embodiment of.

.the invention described herein is only one' l desired position.
